I'm going to lsu cheer camp with my cheer squard in July and I have good jumps but I know I can get them better does anybody have any sugestion to get higher jumps

Stretch ! You can put a leg on the coffee table or something that is elevated from the floor, and I do that while I watch TV , And its helped I now have hyper extended jumps (:

Stretch, do squat jumps too! They help me! Start with your feet apart and then squat and jump when you jump snap your feet together and then back apart for your landing and keep doing them. They really help for your height on toetouches. And running helps with your leg muscles to help you jump higher (:

Lay on the floor with your legs bent but spread apart and push them down. And get a lot of pep and hyperness
